Consumer Health Data Privacy Policy
The short version
- Your health data lives on your phone. We don't keep a copy on our servers.
- We never sell it and never use it for ads.
- Some of it is sent to AI providers only when you use a feature that needs it, like chatting with Big G, and only to answer that request.
- Delete it anytime in Settings › Delete all my data.
This policy explains how Newron Robotics, LLC ("we", "us") handles consumer health data in the GainzGPT apps for iOS and Android (the "App"). It is written to meet Washington's My Health My Data Act and similar laws, such as Nevada's consumer health data law, and it supplements our Privacy Policy. "Consumer health data" means personal information that identifies, or could reasonably be linked to, your past, present, or future physical or mental health.
1. Health data we use
- Body and goal details: age, sex, height, weight, goal weight, weight trend, and your training goal.
- Food and nutrition: meals you log, meal photos you take or pick, and your protein and calorie targets and totals.
- Training: workouts, sets, and progress.
- GLP-1 Muscle Mode (optional): that you use a GLP-1 or other weight-loss medication, the medication and dose day you enter, your main concern, and daily check-ins about appetite and side effects (such as nausea, constipation, fatigue, or reflux).
- Activity (Big G Lock, optional): today's step count and exercise minutes from Apple Health or Health Connect.
- Coach chat: anything health-related you choose to tell Big G.
2. Where it comes from
- From you, when you enter it in the App or take a meal photo.
- From Apple Health (iOS) or Health Connect (Android), only if you turn on Big G Lock with a steps or active-minutes goal and give permission.
3. Why we use it
Only to provide the features you ask for: calculating your targets, building and adjusting your training plan, estimating the nutrition in a meal, answering your questions in coach chat, tailoring guidance in GLP-1 Muscle Mode, and deciding whether your Big G Lock goal is met. We don't use it for advertising, and we don't sell it.
4. Where it's stored
On your phone. We don't run accounts or a cloud database, and we don't keep copies of your health data on our servers.
5. Who it's shared with
We share consumer health data only with service providers (processors) that act on our instructions, only when you use the feature that needs them, and only to answer that request:
| Who | What | Why |
|---|---|---|
| Cloudflare, Inc. | Requests from AI features pass through our Cloudflare-hosted server; meal photos and meal descriptions are analyzed by Cloudflare Workers AI | Running our server and estimating meal nutrition |
| Anthropic, PBC | Coach chat messages and the context listed in our Privacy Policy (including GLP-1 check-in summaries, if that mode is on); meal photos or descriptions if the primary meal estimate fails | Answering coach chat and backup meal estimates |
| U.S. Department of Agriculture (FoodData Central) | Food names only (for example, "grilled chicken") | Looking up nutrition values |
Apple Health and Health Connect data used by Big G Lock is never sent off your phone. We have no affiliates that receive consumer health data. We don't sell consumer health data, and we would ask for your separate, written authorization before ever doing so.
6. Your rights
You have the right to:
- Confirm whether we collect, share, or sell your consumer health data, and access it.
- Get a list of the third parties and affiliates we've shared it with.
- Withdraw your consent, for example by turning off GLP-1 Muscle Mode or Big G Lock, or revoking Health permissions in your phone's settings.
- Delete your consumer health data.
Because your data stays on your phone, you can see and edit it in the App and delete all of it in Settings › Delete all my data (or by deleting the App). For anything else, email privacy@gainzgpt.com with the subject "Health data request." We'll respond within 45 days. If we need more time, we'll tell you why, and we may extend once by up to 45 more days. We won't discriminate against you for using these rights.
7. Appeals
If we decline your request, you can appeal by replying to our decision, or emailing privacy@gainzgpt.com with the subject "Health data appeal." We'll respond in writing within 45 days, explaining what we did and why. If your appeal is denied, you can contact the Washington State Attorney General at atg.wa.gov/file-complaint, or your own state's attorney general.
8. Changes
If we change how we handle consumer health data, we'll update this page and the date at the top, and ask for your consent in the App where the law requires it.
